Jacksonville Sheriff's spokeswoman Melissa Bujeda says arriving officers saw two men and two women had been shot inside the home in Jacksonville's Murray Hill neighborhood. She says one victim was taken to the hospital but later died. The other three were dead at the scene.

Bujeda says investigators are searching for the shooter but didn't offer any further details.

Television stations report that police crews remained at the house on Friday morning. Investigators were canvassing the neighborhood looking for information.

Anyone with information is asked to call the sheriff's office at 904-630-0500.
